Architecture alternatives for PCS-to-Internet protocol interworking

As the growth rate of the Internet subscription increases, the demand for providing wireless access for Internet applications becomes apparent. While packet data networks like CDPD, RAM, and Metricom provide Internet services, their channel capacity is generally insufficient for Internet applications such as Web browsing. Asymmetric high-speed wireless access techniques that support wide-area high-speed Internet applications have been studied and investigated extensively in the industry. However, the network architecture to support interworking of the high-speed wireless access network with the Internet has not been widely discussed. This paper addresses architecture alternatives for interworking of high-speed wireless access network, with Internet backbone for providing a seamless wide-area wireless Internet access service.
